SPECIFICATION forming part of Letters Patent N 0. 493,032, dated March'7, 1893.

Application filed May 21, 1890- Serial No. 352,674. (No model.)

To all whom it may concern.-

Be it knownthat I, FREDERICK J. KALDEN- BERG, a citizen of theUnitedStates, residing at Tarrytown, in the county of W'estchester and Stateof New York, have invented certain new and useful Improvements inSmoking-Pipes, of which the following is a specification.

My invention relates to pipes for smoking, and the object is, in part,to provide means for admitting air to the smoke-passage in the stem inregulated quantities, and in part to provide against the clogging of thepassage in the stem by the liquids which usually collect at the bottomof the bowl.

The invention will be fully described hereinafter and its novel featurescarefully defined in the claims.

In the accompanying drawings, which illustrate anembodiment ofmyinvention,Figure 1 is a longitudinal section of the pipe; and Fig. 2is a detached View, on a larger scale, showing the means for regulatingthe influx of air to the air-passage in the stem.

Heretofore, in the construction of pipes for smoking, various modes havebeen adopted to prevent the clogging of the smoke-passage in the stemwith nicotine, or the thick liquid containing nicotine, but so far as Iam aware none of these have been entirely satisfactory. The constructionembodying my improvements for this purpose is as follows:

The pipe has an inner bowl, 0, to contain the tobacco, and an outerbowl, b, with which the stem is connected. These bowls are provided attheir upper parts, as here shown, with screw-threads, d, whereby theinner bowl is screwed into the outer bowl. When the inner bowl is inplace, as in Fig. 1, a smokechamber, a, is formed between the bowls,which chamber extends up nearly to the tops of the bowls. In the bottomof the inner bowl or receptacle, a, are apertures e, one or more for thepassage of the smoke to the chamher 0.

f is the stem of the pipe. This stem joins per part thereof by atie-piece, h, here shown as in the form of a ball lodged between theinclined stern and the bowl. The stem is furnished with the ordinarymouthpiece, g. A substantially horizontal smoke-passage, t', is formedby boring through the wall of the bowl I), at or near the upper part ofthe smoke-chamber c, thence through the tiepiece 72, into the stem; atthis point there is an angle in the smoke-passage t', which lattercontinues thence upwardly, longitudinally through the stemfto thepointwhere it connects with the smoke-passage k, which latter iscontinued on through the mouthpiece g. This latter is a continuation ofthe stem. The liquid due to the burning of the tobacco and arising fromdistillation and condensation, collects in the chamber 0 below the innerbowl; it may be readily cleaned out by removing the .inner bowl. Thestem f, is solid from the angle in the passage '5 down to the pointwhere the stern joins the bowl b.

In order to admit air to the smoke-pas sage in the stem, to cool thesmoke before it reaches the month,the stem is provided with anair-passage j,which connects at its lower end with an air-inlet m, andat its upper end with the passage is at the point where the passage *6joins the latter. The inlet m is provided with a plate, n, pivoted tothe screwplug, Z, at the inlet, in the manner of a wicket .and adaptedto close, or partially close, as desired, the air-inlet m.

Having thus described my invention, I claim- 1. A tobacco-pipe,comprising a bowl and stem, said stem having a smoke-passage in it whichconnects with the bowl and an airpassage in it which connects at one endwith the said smoke-passage and at the other end with an air-inlet inthe side of the stem, which is provided with means for regulating theinflux of air thereat, as set forth.

2. A tobacco-pipe, comprising an outer bowl, and an inner receptacle ofless size than the hollow in the bowl, whereby an intermediatesmoke-chamber is formed which extends up to the top of the outer bowl atthe sides thereof, an upwardly inclined stem to the mouthpiece of thestem, substantially on the outer bowl, a supplementary stem or as setforth. projection in the angle between the upper l part of the bowl andsaid stem, said pipe FREDERICK KALDENbERG' 5 having a continuoussmoke-passage in said \Vitnesses:

projection and stem which leads from the E. L. BQNNY, upper part of thesaid intermediate chamber W. A. MAIN.
